LOOSE-LEAF BINDER Application filed August 19, 1925. Serial No. 51,109.

My invention comprehends a novel construction and arrangement of a looseleaf binder which consists of but three parts, namely: a fixed partadapted to be connected to a cover, a filler carrying member movablyconnected with said fixed part, and a slide which is adapted to lock thefiller carrying member with respect to said fixed art.

Each of these parts are formed from an integral piece of material, sothat the device can be very economically manufactured.

It further comprehends a novel construction of a fixed member, a novelconstruction of a slide and a novel construction of a filler carryingmember.

Other novel features of construction and advantage will hereinafter moreclearly appear in the detailed description and the appended claim.

For the purpose of illustrating the invention, I have shown in theaccompanying drawing a typical embodiment of it, which, in practice willgive reliable and satisfactory results. It is, however, to be understoodthat ical only and that the various instrumentalities of which my invention consists can be variously arranged and organized, and that theinvention is not limited to the precise arrangement and organization ofthese instrumentalities as herein set forth.

Referring to the drawings:

1 designates the base member of a loose leaf binder, embodying myinvention, and 2 designates a filler carrying member which is hinged tothe fixed member in a novel manner and interlocks therewith by means ofa slide 3. The binder is adapted to be con nected to a cover 4. The'fixed member, the movable member and the slide are each preferablyformed from a single piece of material. The fixed member is formed fromsheet material which is folded to form a rectangular tube with a to 5and the bottom 6, connected by the si e 7 The top 5 is provided with theslots 8 which are enlarged as at 9, see Figure 3. The top isalsoprovided with the openings 10. The top is deflected downwardly as at11, see Figure 5,

and it merges into the intermediate portion 12, so that a space isformed between the top 5 and the intermediate portion 12 to receive theslide 3, which is also formed of a single piece of sheet material whichis deflected upon itself to form the top member 13 and the bottom member14.

It will be understood from the foregoing that the fixed member issubstantially rectangular in cross section, with the free edges 12 and 6overlapping.

At one end the slide is deflected as at 15 to form a grasping handle,and the slide in proximity to its end 'is apertured, as at 16, and it isprovided with bayonet types of slots 17 which are preferably of the samecontour as the slots 8 in the top 5 of the fixed member.

The ends of the fixed member 5 are bent downwardly and inwardly and havethe terminals 18 which pass through the cover 4 and the bottomportion 6ofthe fixed member 5 in order to secure the binder to, the cover. Thepurpose of the openings 16 in the slide and the registering openings 19vin the fixed member 5 is to enable one to insert a tool through suchopenings to clinch the ends 18 of the fixed member 5, see Figure 4.

The filler carrying member 2 is formed from a single piece of materialand as illustrated, it is bent upon itself to form the filler retainingloops 20, and it is also defiected upon itself to form the hooks 21,which may be located at any desired point in the longitudinal length ofthe filler carrying member 2, and, as illustrated, each loop has inproximity to it one of the hooks 21 Instead of forming the hook 21 fromthe longitudinal stretch of the filler carrying member, a fillercarrying member 22 may be employed in which the loop 23 terminatesin ahorizontally extending hook 24, which, as seen in Figure 11, is lockedand unlocked by the slide 3, and the openings 25 which correspond to theopenings 8 and 9 are located in the opposite side of the casing fromthat seen in Figure 7 In the operation, when the slide 3 is movedoutwardly, it will be apparent that the hooks 21 will be brought intoregister with the enlarged portion 9 of the openings 8 and with theenlarged portion of the openings of the slots 17, so that the fillercarrying member can be swung backwardly and the leaves of the fillerinserted or removed as may be desired.

The operation of the filler carrying member seen in Figures 10 and 11 issimilar to that already described, since when the slide is movedoutwardly the hooks 24 will be unlocked and when said slide is movedinwardly the hooks 24 will be locked.

The fixed member or casing can be very cheaply manufactured from sheetmaterial, and, at one end, the top is bent downwardly to form the meansfor securing it to the cover, and, at the opposite end, one of theferent openings of the slots in the slide and I the casing can be formedat the same time the blank is cut from sheet material.

It will now be apparent that I have de-' vised a new and useful looseleaf binder which embodies the featuresof advantage enumerated asdesirable in the statement of the invention and the above description,and while I have, in the present instance, shown and described apreferred embodiment there-v A loose leaf binder, comprising a basemember folded to form a rectangular tube,

a fill'er carrying member hinged to said base member, provided withfiller retaining loops and with a hook, and a slide in said tubular Ymember cooperating with said hook to secure said loops in their lockedor unlocked position, said base having deflected ortions to secure it toits cover, and said use and slide having registering openings to receivea tool to clinch the ends ofsuch portions.

bottom laterally extending portions is bent downwardly to form the meansat such end for securing the fixed member to the cover.

The slide is formed from a single piece of material which istransversely folded upon itself, the bottom being of less width than thetop. The slide is contained within the fixed member so that when theparts are assembled the longitudinal stretch of the filler carryingmember will be retained in hinged relationship with respect to the fixedmember or casing which carries it.

It will be apparent that since each of the three parts are formed from asingle piece of material that my present construction of loose leafbinder can be economically manufactured, and, at the same time, it willbe durable and reliable in practice. The dif-
